Personal best as of 2026/04/29.
April 29 is Pixel's birthday, and on this day the title screen music in Cave Story+ changes to the Ikachan theme. But in CS+ Switch, there is a bug where with the original soundtrack, _every_ track changes to the Ikachan theme, even the normally-silent track 0 that's used when there's supposed to be no music playing. A few years ago, I did a speedrun of this same category on this same day with the bugged music: youtu.be/9Xc3PYnISBE . This year, I decided to run it back again to get the sub-11.

Only minor quiz spoilers here. If you want to test your own Cave Story IQ first, go here: https://doukutsuclub.knack.com/database#search-database/mod-details/5ce12d882acb7100072dc926/
The time trial mode of this mod is unlocked after completing the normal quiz and features only the questions that have non-trivial execution (i.e., more than just pick the correct answer).
The spikes are _supposed_ to hurt you, but with subpixel-perfect precision (1/512th pixel) you can slip in between them without taking damage. (Dont try it at home, youll never get it.)
I deliberately answered Q45 incorrectly because it would have been much slower to get the correct answer. Thankfully, its not required to complete all of the questions perfectly in order to finish the time trial. :P
Fun fact: I realized after making this TAS in Hourglass and then trying to encode the video that there were some...issues with using Hourglass for this (mostly with the weird framerate of the game, and that I had mistakenly specified the wrong framerate for the movie). So I had to make a Linux port so I could dump the video through libTAS instead.
btw Enlight, wtf is that MOD command, it makes no sense-")

For those who dont know, AISSON is a Game Genie code that allows Mario to go through walls. (But only from the left side, technically)
Anyways, some people have been asking for this, so here you go. There is probably still a frame or two (or more) to save in 8-4.
I wasted some frames in basically every level except 4-2 and 8-4 for entertainment, because all of those other levels have super lenient framerules.
Shoutouts to KrillerCoinCount and KrillerStartFrame :)
(actually, the latter might be off by one, oops)
Oh, also, I used L+R in this TAS, which goes against the RTA category rules. Sorry :(
